Best i can remember, it's hanging on the firewall on passenger side next to the heater/Ac box. Think there is 3 relays there, unplug each until blower stops. Then you know which it is! Sure sounds like it is stuck closed! It's an unswitched circuit to the relay.
Thank you very much "PushRod".....that is where the relay was located and the contacts were "closed".
New relay in....problem solved!
COOL! Glad to help. Thanks for the reply, that may help others with the same problem!
